Summary: MarshalException in serializing Handle
Initial Comment:
I have the following code:
// userSession is stateful session bean
Handle ser = userSession.getHandle();
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject(ser);
this throws the following exception:

A javax.ejb.Handle is supposed to be serializable so
this should work.

My problem is similar to yours. I tried to save the
RemoteInterfaceHandle of a Stateful Session Bean in
HttpSession with the same errormessage as a result.
javax.ejb.Handle is an Interface, so what really is stored in
the session is the implementation of that interface.
I found out
that "org.jboss.proxy.ejb.handle.StatefulHandleImpl" which
implements "javax.ejb.Handle" contains an instance
of "org.jboss.invocation.Invoker" which seems to be not
serializable (respectively the class that implements the
invoker-
interface: "org.jboss.invocation.jrmp.interfaces.JRMPInvokerPr
oxy").
Don`t know, if that helps or if that is the root cause of the
error but I hope that something about this problem is done or
at least a workaround is presented.

I did encounter the same difficulties. The handle of a SSB you
obtain in a java application is serializable, while the handle
you obtain inside JBoss is not.

JDK 1.4.0_01
with
JBoss 3.0.0_tomcat-4.0.3, JBoss 3.0.1_tomcat-4.0.4, JBoss
